Abstract

본 발명은 TV에 있어서, 화면의 밝기에 따라 칼라망을 자동으로 조절하는 칼라양 자동 제어 장치에 관한 것으로, 입력되는 복합 영상 신호를 적분하여 일정 레벨의 DC전압으로 변환하는 적분기(21), 외부의 칼라량조절 신호가 입력되면 이를 디코딩하여 칼라량 레벨을 제어하기 위한 기설정 전압을 출력하는 제어부(22),입력되는 색차신호를 각각 증폭하는 증폭부(24), 상기 제어부(22)와 상기 적분기(21)의 출력전압을 수신하여 휘도 신호가 정상 레벨일때의 적분기(21)의 적분 전압과 상기 제어부(22)의 출력 전압을 향한 전압에 의해 사용자가 설정한 칼라량으로 조정되도록 상기 증폭부(24)의 중폭도를 조절하고 상기 휘도 신호의 레벨이 정상 상태보다 높아지거나 낮아짐에 따라 변화하는 적분기(21)의 적분 전압의 변화량에 의해 사용자가 설정한 칼라량이 자동으로 미세 조정되도록 상기 증폭부(24)의 증폭도를 조절하는 칼라량 조정부(27)를 구비하여 구성함을 특징으로 한다.The present invention relates to a color quantity automatic control device for automatically adjusting a color network according to the brightness of a screen in a TV. An integrator (21) for integrating an input composite video signal and converting it into a DC voltage of a predetermined level is external. The control unit 22 outputs a predetermined voltage for controlling the color level by decoding the color amount control signal when the color amount control signal is input, an amplifying unit 24 for amplifying the input color difference signal, and the control unit 22 and the The amplifier unit receives the output voltage of the integrator 21 and adjusts the color amount set by the user by the integral voltage of the integrator 21 when the luminance signal is at a normal level and the voltage toward the output voltage of the controller 22. The amount of color set by the user is controlled by the amount of change in the integral voltage of the integrator 21 which is adjusted as the level of the luminance signal is adjusted higher or lower than the normal state. Characterized in that the configuration provided with a collar amount adjustment section 27 for adjusting the amplification degree of the amplifier section 24 such that the fine adjustment.
